They are economists. Or at least one of them is. Not sure if both.
But if you are professional economist to keep a job you nearly have to lobotomize yourself. You simply must be an IYI to maintain your salary.
What we have been seeing worldwide, from India to the UK to the US, is the rebellion against the inner circle of no-skin-in-the-game policymaking “clerks” and journalists-insiders, that class of paternalistic semi-intellectual experts with some Ivy league, Oxford-Cambridge, or similar label-driven education who are telling the rest of us 1) what to do, 2) what to eat, 3) how to speak, 4) how to think… and 5) who to vote for.
That describes the duo on that site perfectly.
Mystery solved. IYIs, and the worst sort of IYIs: economists!
